Being slow at gym or while practicing athletic performance is not a positive sign as it shows low energy levels. But being slow in digestion, casein protein is great at increasing energy levels & stamina. Extracted from milk, casein is rich in essential & non-essential amino acid that is a must have for people engaged in intense training workout. Casein slowly & steadily releases amino acids into the bloodstream for constant 8 hours. When taken at night, this constant flow of aminos keeps the body fed and prevents the action of catabolic enzymes that get active when there is no nutrition flow. This way casein works great in maintenance of muscle mass, replenishing the lost energy level and promote muscle growth. To know more visit www.getfitness.in .
